SPECIFICATION forming part of Letters Patent No. 393,559, dated November 27, 1888.

Application filed August 3, 1888. Serial No. 281,874.

To all whom it may concern.-

Be it known that we, JOSHUA Honor, of the city and county of San Francisco, and ORANGE M. LovERIDeE,of Weaverville, Trinity county, State of California, have invented an Improvement in Hydraulic Mining Apparatus; and we hereby declare the following to be a full, clear, and exact description of our invention.

sc Our invention relates tothat class of apparatus for hydraulic mining in which ajointed nozzle is used to direct a powerful stream of water against a bank or other workings; and our invention consists in a novel improvement :5 in the construction of the ball which forms the joint of the nozzle-pipe.

The object of our invention is to increase the capacity of the nozzle.

Referring to the accompanying drawings for amore complete explanation of our invention, Figure 1 is a side elevation of a hydraulic mining apparatus showing our improvement. Fig. 2 is a section of same at the point or" improvement.

A is an elbow-pipe, and B is another, the two beingjointed at a in such a way that the elbow B may turn on the elbow A to any angle throughout the circle or circumference of its joint. The elbow B is provided on its forward end with a ball, 0, having an exitopening, 0. To the ball is pivoted by trunnions d a flange or ring, D, to which the flaring rear end, 0, of the nozzlepipe E is bolted, said flaring end thus fitting over the forward end of the ballG and having anup-and down move ment thereon about the trunnions d as acenter. A packing-ring, F, bolted between the nozzle pipe and ring D, bears on the ball and makes a tight joint. This is the usual construction of thisjoint. Our object being to increase the capacity of the apparatus, we found that, with the construction of the joint as shown, it would not answer to simply increase the diameter of the exit-opening c, which has heretofore been round, for in that case, as the pipe E moves up and down, the packing-ring F would be exposed. Therefore the diameter of the opening 0 was necessarily limited; but as the pipe does not move sidewise on this joint we have found that we can obtain the (No model.)

desired enlargement for increase of capacity by recessing or cutting baekwardly the sides of the exit-opening, as shown at 0'. Now, as the pipe does not move sidewise, these additional openings or recesses do not expose the packingring, and the pipe may move up and down, as before. By this improvement we have effectually accomplished the necessary result and materially increased the capacity of the nozzle without interfering at all with 5 the perfect construction of the joint itself.

The movement of the nozzle-pipe is effected by a system of levers,(designated generally by G, and which need no detailed description, as they form no part of our invention.)

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a hydraulic nozzle, a ball to which the nozzle-pipe is fitted, forming a joint on which said pipe may move up and down, said ball having an exit-opening in front with backward] y recessed or cut-outsides, substantially as herein described.

2. In a hydraulic nozzle, the combination of the nozzle-pipe, the flange or ring to which the said pipe is bolted, and the ball to which the flange or ring is pivoted, whereby the nozzle-pipe may move up and down, said ball having an exit-opening in front with back s ward] y recessed or cut-out sides, substantially as herein described.

3. In a hydraulic nozzle, the combination of the nozzle-pipe, the flange or ring to which said pipe is bolted, the intervening packing- 8 ring, and the ball to which the flange or ring is pivoted,whereby the nozzle-pipe may move up and down, said ball having an exit-opening in front with backwardly recessed or cut-out sides, substantially as herein described. 0

In witness whereof we have hereunto set our hands.
